In mammals, sex is usually preceded by intricate mating behaviors. Indeed.

This family tree reveals that sexual populations have recently and repeatedly spun off asexual strains. I would think that some environmental stress would cause the spin off of an asexual strain. Perhaps a die off of prey or a particularly cold year.

sex appears to have enabled the separation of beneficial and deleterious versions of genesIs this where can I get me one of those sex licenses?

“When sexual species reproduce asexually, they accumulate bad mutations at an increased rate”
Take note. CLONING is reproducing asexually, so CLONING will cause big trouble with abnormal mutations.

"Scientists have long been left to ponder, what is it about sex that justifies its big energy investment?"Doesn't have a clue, does he? And people wonder why scientists are considered to be nerds.

The scientists sequenced the entire mitochondrial genomes...and...found the asexual lines have accumulated bad mutations four times faster than sexual lines.This is confusing. At least in humans, mitochondrial DNA is supposed to be asexually reproduced, coming only from the mother. Is that not the case with water fleas?

Sexual reproduction is biologically costly and at times complicated. In mammals, sex is usually preceded by intricate mating behaviors. It requires the compatibility of sexual structures, an insertion event,... New recommended pick up line, "Want to take part in an insertion event?"

The ability to reproduce asexually may be useful to organisms that can't get mates, but its long-term benefits are questionable.If I sit here long enough, I'll double in size?

"Ultimately, we would like to know how long a species can abstain from sex without going extinct," Lynch said. I wonder if we can volunteer the species of Liberalis Americanus for the above mentioned experiment...
